“…Simultaneously, the QCM shows a mass increase (frequency decrease) from 0 to −1 V, in line with the cation insertion rather than the expulsion of the StySO 3 anions. When the film is reduced, this observation is in contrast to the behavior of the PPy/toluene sulfonate resin that lost the major part of the anions upon reduction [17]. Assuming that volume and hydrophobicity of these two anions (p-toluene sulfonate and styrene sulfonate) are quite comparable, the difference observed might be accounted for by the reaction of the double bond of StySO 3 with growing PPy, so leading to the irreversible incorporation of these anions to the resin.…”

“…42 Also, since cations normally move faster than anions, the charge transport rate in the PPy/PSS composite will be faster. 43 There are numerous reports on the electrochemical generation of PPy in the presence of PSS, and the exploration of the properties and applications of PPy/ PSS composites, [44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59] but there is only one report describing the chemical synthesis of PPy in the presence of PSS. 36 Our current interest in PPy/PSS is as a catalyst support in proton-exchange membrane fuel cells.…”

Size control of polypyrrole particles prepared by chemical polymerization was achieved by varying the concentration of the oxidant in the presence of poly(styrenesulfonate). At higher concentrations, smaller polypyrrole particles are formed. Poly(styrenesulfonate) functions as a molecular template, causing local preconcentration of both pyrrole and Fe3+. These increased local concentrations result in faster nucleation and polymerization, which favors the formation of small particles. Average particle sizes ranging from ca. 40 nm to 1 μm have been obtained.

“…. ) 8,9 has already been reported. Since the cations are not reduced to the metallic state in water and no intermediate oxidation state (i.e., Th 3ϩ , La 2ϩ , or Ba ϩ ) is known, only electrostatic interaction between these cations and the polarized PPy resin can occur.…”
